Hi,
        Here's another interesting one, and a bit more annoying (in
        reverse video anyway).

        The console on the internal video is shifted about 4 pixels up
        from the bottom of the screen. So half the top line of text is
        off the top of screen.

        The 4 pixel rows at the bottom of the screen are filled with the
        familiar grey checks of the mac OS background.

        Could this be something to do with the "LC474-575 Video Address
        Hack" that I have to use to get the console (on this LC575) ?

        On booting there is something about the video address being set
        to 0xb87000 (this is before the dmesg output): is this 4*640
        pixels to low?
Thanks,
Don
